Basic fibroblast growth factor or fibroblast growth factor-2 (FGF) has been shown to affect myeloid cell proliferation and hypothesized to stimulate primitive hematopoietic cells. We sought to evaluate the effect of FGF on hematopoietic stem cells and to determine if FGF mediated its effects on progenitor cells directly or through the induction of other cytokines. To address the direct effects ...

Rabies is an infectious viral disease without any cure. Autophagy considered as a method for reducing the damage to cell and its organelles. In some virus-infected cells, autophagy plays antiviral effect, while it acts in opposite manner other cells. Beclin1 (Atg6/Vps30) main regulator of autophagy. The present study aims build recombinant beclin1 stimulating evaluating effects mice infected wi...

background: as condition and component of culture determine fate map of spermatogonial stem cells (sscs), the aim of this study was to evaluate of growth factors gdnf, lif and ra on proliferation and differentiation of ssc. materials and methods: sscs were cultured in two groups: the first group gdnf and lif and the second group ra. the number of clumps and colony formation was monitored during...

It has been suggested that the BCR-ABL gene of chronic myeloid leukemia (CML) is not uniformly expressed in Philadelphia (Ph)-positive cells, and that BCR-ABL gene expression precludes transcription of the normal BCR or ABL genes. Therefore, we have analyzed granulocyte-macrophage colony-forming unit (CFU-GM) colonies derived from peripheral blood of 11 CML patients by cytogenetic and by revers...

In order to determine genetic variability among 33 isolates of Fusarium semitectum, morpho- logical and molecular studies were carried out. Isolates from different paddy fields in the north of Iran were separated from each other in four morphotype groups. The isolates showed a high level of variation in aerial mycelium, color of colony, number of septa and growth rate on potato dextrose agar (P...

Background: Contagious agalactia causes significant economic losses. The aim of this study is to investigate the presence contagious disease in cities Isparta and Afyonkarahisar, Turkey. Methods: includes 45.500 animals 220 ovine enterprises samples were taken from those suspected disease. 202 21 comprised 139 goats, 56 sheep, 3 kid 2 lambs total sampled. A 289 collected, including 91 milk samp...

Purpose: As a newly cultivated grass species widely used in saline-alkali soil treatment, Juncao"Oasis No.1" can effectively enhance the microbial population abundance soil. It has good effect on improving Methods: In order to further study community rhizosphere of No.1”, dominant strains with important ecological value were screened out. this paper, samples collected from planted No. 1" and un...
